You meant storage memory, correct?

Yes, hard drive space. I supposed it was the cache data created by AT for building the VT.
AT continued to process quietly even after the Windows was complaining about the disk being full. Maybe AT was then working at a slower rate if more operations were ...

That's odd, the resulting virtual texture should be considerably smaller than the original assets

It is. The resulting VT is about 380 GB (I suppose it's the big file in Library\AmplifyCache since I can see no other big file in the project folder) whereas the initial set was 428 GB. It's while AT ...

Hello,

Yes, this is the 88x64 8k tileset mentionned earlier, it takes 428 GB on disk.
The VT is built with a "Amplify Texture/Legacy Shaders/Nature/Terrain/Diffuse" material and Vt properties are set to the following :
- HW level = Ultra
- Virtual Size = 1024k x 1024k
- Tile size = 512 x 512
- Mip ...

Hello,

Still no success after adding the missing tiles as 8192x8192 black images and setting the first tile to the same resolution, but this time the process ended up with an all black VT, 2 errors, and warnings (I'll paste them at the end of this message)

My hard drive was full at the middle of ...

It turns out that my first tile is a dummy black tile that has not the good resolution (it was not obvious in the Unity Editor which doesn't display the 'real' resolution...), it must be why the downscaling occurs...

I'll scale this guy to the 8192x8192 and try again, leaving all the missing tiles ...

Hello,

Just a quick update : I've created the missing tiles as symlinks targeting one black tile. I've hit the Rebuild button on the VT inspector, and the material seems to have been reset since it's y-flipped again.
=> No noticable change in the VT resolution.

Now I'm going to create real ...

Thanks for your answers !

By grid, do you mean the actual tile values in the material?

By grid I mean the set of textures as detected in Unity material inspector.
As an example of what I meant, this is a 4x4 grid as detected in Unity inspector :
t t t t
t t t ?
t ? ? ?
t ? ? ?
't' are provided ...

Hi

I'm currently using the Amplify Texture trial version in Unity 5.4 terrains, and it seems to be a very interesting tool to have when dealing with GIS. I'm interested in that product so I'm trying to evaluate its limits. I'm usually working with multiple 8192x8192 png tiles and a _x#_y#.png ...
